| Outline of Final Research Achievements |
(1) We performed a gene trap screen using the Tol2 transposon system and identified a large number of transgenic fish expressing Gal4FF specifically in various cells, tissues and organs. We analyzed the transgenic fish by Southern blot and PCR, and mapped the transposon insertions on the zebrafish genome.
(2) We conducted collaborative research with experts of the studies of developmental biology and organogenesis based on the transgenic fish lines expressing Gal4FF. The results were published as 40 articles written in English.
(3) We succeeded in developing a system using the botulinum toxin gene that can efficiently inhibit the function of Gal4FF expressing neurons. By performing calcium imaging, we discovered a neural circuit that connects a visual stimulus with the inferior lobe of the hypothalamus, which is the center of appetite. We succeeded in identifying a neuronal population in the telencephalon, that is essential for fear conditioning.
